The study develops a modular fusion protein strategy (SP-cBG-HL4) to provide broad-spectrum resistance against three major potato pathogens: Phytophthora infestans, Alternaria solani, and Ralstonia solanacearum. By combining antimicrobial proteins and immune-inducing patterns with optimized linkers, the researchers successfully enhanced plant defense responses and reduced disease symptoms.
This study develops a non-destructive method for the early detection of potato tuber dry rot caused by Fusarium spp. using near-infrared hyperspectral imaging and a dual-branch ResNet12-SE deep learning network. The model achieves high accuracy in identifying early-stage infections, providing a potential high-throughput screening tool for postharvest potato quality management.
This study evaluates computer vision object detection models for AI-operated mobile potato harvesting, specifically comparing a 3-label classification scheme (potato, stone, soil clod) with a merged 2-label scheme (potato, impurity). The findings demonstrate that using fine-grained 3-label supervision significantly improves impurity detection precision and representation quality during harvesting, despite both impurity types triggering the same physical sorting mechanism.
This study evaluated predictive breeding models combining genomic SNP markers and UAV-derived phenomic data across diverse potato clones. Integrating genomic and phenomic data significantly enhanced prediction accuracy for total tuber yield compared to using either dataset alone, while genomic data proved superior for predicting starch content. The findings demonstrate that combining multi-modal data can optimize selection strategies and accelerate genetic gain in potato breeding programs.
This study characterized the physicochemical properties of raw potato starch (RPS), revealing round to oval granules with a B-type crystalline structure. It further evaluated RPS as a dietary resistant starch, demonstrating its protective effect against enteritis-induced bone loss and systemic inflammation in meat ducks.
This study demonstrates that adding olive oil to potato protein-stabilized double emulsions enhances interfacial interactions and promotes stable protein structures. The optimized formulation significantly improves probiotic protection and viability during freeze-thaw cycles, long-term storage, and in vitro digestion. These findings highlight a promising potato protein-based delivery system for functional food applications.
This study identified and characterized Toll signaling pathway components in the potato psyllid (Bactericera cockerelli), a vector that transmits Candidatus Liberibacter solanacearum (Lso) in solanaceous crops. The authors demonstrated haplotype-specific gene expression responses of Toll receptors to LsoA and LsoB acquisition, as well as induction by the entomopathogenic fungus Beauveria bassiana. These findings provide insights into vector immune responses and potential targets for managing psyllid-transmitted potato diseases.
This study identifies PVYN-Wi isolates as a cause of external tuber necrosis and cracking in potato crops in the San Luis Valley, Colorado. Because PVYN-Wi belongs to the O-serotype, it evades standard N-serotype antibody detection used in seed potato certification programs. These findings highlight the need to update PVY diagnostic and management strategies to better protect seed potato quality.
This study describes an efficient semi-selective culture medium (ClaYPGA/ClaYDC) combined with a highly specific PCR primer pair for the isolation and identification of all *Clavibacter* species. Because *Clavibacter* includes major agricultural pathogens such as *Clavibacter sepedonicus* (the causal agent of potato bacterial ring rot), this method provides an improved diagnostic tool for potato pathology and plant quarantine monitoring.
This study investigates how temperature and geographic population differences affect the efficacy of RNAi-based insecticides against the Colorado potato beetle, a major potato pest. The findings suggest that cooler temperatures reduce the effectiveness of gene silencing and mortality rates, which has significant implications for the timing and regional application of pest management strategies in potato cultivation.
